854-4 I/O Rating/Circuit4-4-1 Input rating and input circuitThis section shows the input rating and the input circuit for the I/O terminal block input and the I/O connector input. Notethat the input rating and circuit of INTERLOCK terminals (X16, X17, X18, X19) are different from those shown here. Refer to“4-4-3 Interlock terminal rating and I/O circuit” (P.87).

However, the wiring from I/Oterminal block and the I/O connector respectively cannot be used as NPN/PNP mixed. Operate the product afterselecting either NPN or PNP.• Do not short-circuit 24V OUT (X1, Y3) and 0V OUT (Y1, X3). Also, do not short-circuit IN COM. 1 (X2) and OUT COM.2(Y2, X12). Starting the laser marker with these terminals short-circuited will cause the laser marker to malfunction.ンㄆㄇㄆㄓㄆㄏㄆ• Respective inputs are bidirectional photo-coupler inputs. The regulation for input ON is based on the ON status of photo-coupler.• IN COM. 1, OUT COM. 1 of the I/O terminal block and IN COM. 2, OUT COM. 2 of the I/O connector are independent.If you use the I/O connector terminal, connect input common/output common of the I/O terminal block and the I/Oconnector to power supply respectively.• DC 2-wire sensor cannot be connected to any input.ME-LPGS-SM-8
